T a/ZZ whom t mag/concern,.-

Be it known that we, WILLIAM P. LocKE and HENRY D.MINNIcK,citizens of the United States, and residents of Canton, in the county of- Starl; and State of Ohio, have made certain new and useful Improvements in Siphons, of which the following is a specification.

Our invention is an improvement in that class of siphons which are provided'with'a starting attachment consisting of air-exhausting mechanism. In our invention the liquid is received into a chamber which is provided at one end with a collapsible bulb and at the other with an outlet-valve, other` valves being provided for controlling the escapeof air;

tral longitudinal section illustrating the operation of the main portion of the apparatus when air is being extracted from the Siphontube and receiving-chamber. FIg. 4 1s a similar section showing the position of certain parts when liquid has been received into the chamber and is discharging therefrom. Figs. 5 and 6 are perspective views illustrating Ameans for locking a spring-Valve contained within the liquid-receiving chamber and serving tol control the escape of air. Fig. 7 is a plan view of the device employed for supporting the siphon attachmentupon a bottle.

Fig. 8 is a perspective view of the device employed for supporting a Siphon-hose in the holder from which the liquid is drawn.

Referring' in the first instance to Fig. 1, A indicates the liquid-receiving chamber with Vwhich the fiexible hose B is connected. (See valso Fig. 2.-) The said chamber is provided with screw-caps ct and a at its respective ends. f The upper cap a has a tubular extension c2, to

which a collapsible bulb C is attached.. As

. shown, the extension L2 has a circumferential corrugation `or rib for holding the bulb se-i.

curely attached and also an opening a3 at its upper end. Thelower cap a is dished or concaved to permit the outiiow of liquid and provide a seat for an elastic washer CZ, which-is attached to the outlet-tube D. The latter is adapted to fit neatly but also slide in the tubular extension of the cap et. The aforesaid washer d is secured by a screw to the thickened head of the tube D, and the latter is provided with a series ofvadjacent openings CZ',

through which the liquid escapes from thev `chamber A and a cross-piece or. spider E, The invention is embodied in the construcwhich is fixed in thetube D and in use rests upon the neck of the bottle or other receptacle Y for the liquid, is arranged a spiral spring F,which encircles the tube D, as shown. The saidcross-piece E (seeFig. 7) has radial arms, as shown, and one of them is providedI with a spring-catch Gr, which is adapted to engage the iiange; t5 in a certain contingency, as" will be hereinafter explained.

Within the tubular extension a2. of the chamber A is secured a centrally-perforated plug as. VIn the upper end of the same is located a check-valve H, which seats downward. vThe Figs. l, 5, 6,)` consists of a valve proper, J,

and spring-support K. The said support is formed of a plate-spring so bent that it has two horizontal members, the upper one having an opening 7c, which adapts it for attachment to the lower end of the plug a, and the lower one a smaller opening c', which provides for attachment of the valve proper, J.

The free end ofthe upper member of the spring is bifurcated and bentdownward, and a plate-lever L is suspended and adapted to rock therein by means of an axis Z. (See Fig. 5.) The upper end of the plate-lever L is curved-outwardly and provided with a hori- Zontal opening' Z/, which is adapted to receive TOO the end 7:2 of the lower member of the spring l and this indicates that the siphon is ready for K. The arrangement is, however, such that this engagement cantake place and be maintained only when the plate-lever L is in vertical position or adjusted to the right of such position, as shown in Figs. 1, 3, 4. In other words, when the lever L is thrown to the left, as indicated by dotted lines. Fig. 4, it is disengaged i'rom the valve-spring K, as will be readily understood.

A device M, which may be termed a button, is arranged in connection with the upper cap L o1 the liquid-receptacle for throwing down the lower member or' the spring K for the purpose of removing the valve J from its seat, as indicated in Fig. 3, and at the same time locking the valve-spring in engagement with the plate-lever L. The said button consists of a push-rod which slides in a suitable holder, its lower end resting. upon the lower member ofthe spring K and its upper end being enlarged to form a head. Between the said head and the holder in which the rod l slides is a spiral spring m, that serves to hold ber A may be made of glass, in which case the the device normally elevated, as shown in Figs. l and 4.

We will now describe the operation of the apparatus. By pushing the button M downward the lower member of the spring K is forced downward until its end engages the notch or slot Z' in the lever L. Thus the valve J is removed from its seat and held removed by the locking engagementoiI the spring with the part L. It is apparent that the curved form of the upper portion of the valve-lever L enables this engagement to be easily et'- fected, the part L swinging on its axis as required for the purpose. rJhe free end of the hose B having been first immersed inthe liquid-holder X, (see Fig. 2,) the bulb C is squeezed and thereby collapsed, (see Fig. 3,) and then being allowed to expand the air contained in the hose B and the chamber A is drawn out through the passage provided by the parts a and ft2 into the bulb-chamber, as indicated by arrows. By squeezing the bulb a second time and allowing it to expand it is again refilled with air, and this may be repeated, it' necessary, for the purpose ot' thorough exhaustion of air,` whereupon the liquid will begin to flow from the receptacle X and ill the chamber, as indicated in Fig. 4. In entering the cham ber the liquid exerts suihcient force to throw the lower end ot' the lever L to the left or away from the mouth of the inlet e7, whereby the lower member o1 the spring K is released and the valve J allowed to resume its seat on the nlug a, thus closing the latter, so that no liquid can be sucked into the bulb. The body of the chamoperator may readily perceive the height of the liquid therein; but he will be apprised when .the chamber is filled by reason of the fact that the bulb C does not readily expand,

continuous action. The end of the tube l) is then inserted tothe cross-piece or spider E, the cross-piece resting upon the bottle or other holder which it is desired to lill. 'lhen by downward pressure upon the body ot' the chamber the tube D is forced upward through the tubular extension a" of the chamber A, as shown in Fig. 4, so that the openings d oi tube D are carried above the cap a. It is apparent that when the parts are held in this position the liquid will l'low continuously so long as any liquid remains in the holder. In other words, the liquid will continue to liow so long as the air-pressure on the body of liquid in X is maintained. Since it would be somewhat inconvenient to lnaintain this pressure upon the spring F for holding it compressed, as indicated in Fig. 4, the springcatch Gr will be engaged with the iange af. as there indicated. When the receptacle Y has been filled, a slight downward pressure upon the chamber will release the spring` G from engagement, and the chamber being allowed to rise by the expansion of the spring F the washer d will again seat, as shown in Figs. 1 and 3, and the flow of liquid from the chamber be thus cut ed. It is obvious that the apparatus may then be applied to another receptacle and the operation repeated at will, or the apparatus will remain indelinitely ready for immediate liow whenever required. lt is further apparent that the bulb need not be again manipulated, since the chamber will remain fully charged so long as the t'ree end of the hose B is immersed in the supply-tank or holder X.

A small opening Z2 is provided in the tube D at such a point that when the latter is in the normal position, as shown in Figs. i, 3, air is admitted to induce perfect drainage ot the tube D. Tithout this provision a certain amount ot' liquid, more especially il the same be of a vscid natu re,would be retained in the tube and drip slowly out and go to waste.

1t will be seen that by our improved apparatus the liquid is never admitted to the bulb. The tree end ot' the hose B is provided with a perforated tube (see Fig. 2) for the purpose of preventing any solid matter being drawn in.

In Figs. 2 and 8 we illustrate an improved device N for supporting the hose B in the liquid holder or tank X. lt is formed of springwire and its general form approximates that of the letter V. There is a central coil adapted to receive and embrace the hose B, and each of the two divergent arms has two outwardlyprojecting shoulders, which are formed by bends of the wire. It will be seen that these shoulders serve to prevent the device moving upward or downward when duly adjusted in position, as shown in Fig. 2. When the arms are pressed toward each other, the device will slide easily on the hose; but when allowed to IOO I- chamber, a collapsible bulb connected there- 1 expand the coil tightens on the hose and the latter is held with sulicient friction to prevent its sliding in the holder.

What we claim is- 1. The improved siphon attachment comprising a liquid-receiving chamber, a collapsil ble bulb applied thereto and valves permitting the outflow of air and preventing the flow of liquid into the bulb, an outflow-valve connected with the chamber, and a valve arranged within the chamber and serving to close the outlet to the bulb, and means for unseating said valve as required for startingthe siphon, substantially as described.
